Hi Jagrat,
Thank you for contacting the Microsoft Community.
I recognize how valuable the 50% discount is in significantly lowering the cost of the AZ-900 exam. Let me walk you through the key details to help make the process as smooth and straightforward as possible.
Please be advised that as per the sticky post, Microsoft Virtual Training Day is now voucher-less, the 50% discount will automatically be applied at the checkout page. To do this, you have to ensure to log in to your Learn profile using the email address you used to sign up for the training event when scheduling the exam. This is because the discount is linked to that specific email only.
If you have already tried scheduling the exam using the email you registered for the event and the discount did not appear at the checkout page, please provide a complete recording starting from the login page showing the email address you used for the training event up to the checkout page where the discount was not applied. For Windows devices, use the Snipping Tool to record the steps. Open the tool, select the video icon, click "New," draw the area to record, press "Start" to begin, and "Stop" to end the recording. For MAC devices, follow the instructions provided in the link. Kindly upload the file through the private message that I initiated along with the requested information.
For additional details on Microsoft Virtual Training Day events, you can check out our sticky post. Additionally, you may explore the Microsoft Events Catalog, Microsoft Learn blog and FAQs section for information on available training events that include exam vouchers and answers to frequently asked questions.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages. Thank you.
Kind regards,
